App Detective is a free utility for Android devices that can be used to get information about the installed applications on your device, including the package name, the version, and even the size.

Once you have the information, you can use it to get a more detailed look at the specific app. You can see what the app is, who is the developer, what is the app's purpose, and even see if there are any security or privacy issues.

There is one thing that you need to be aware of, though, and that is that this utility will not work on any device that is not an Android one.
